an acronym is a word formed from the initial letters of words in a set phrase. define a function named createacronym that takes two string parameters: userphrase and useracronym. function createacronym() then assigns useracronym with the acronym of userphrase. append a period (.) after each letter in the acronym. if a word begins with a lower case letter, don't include that letter in the acronym. then write a main program that reads a phrase from input, calls createacronym() with the input phrase as one of the arguments, and outputs the resulting acronym. assume the input has at most 50 characters and contains at least one upper case letter.
